I am not familiar with Mate and so I do not know whether something concerning these notifications is specific to Mate. I also do not know whether there are any undesired print status pop-ups on Mate's desktop.
I only know that after the system-config-printer fix any undesired pop- ups disappeared on standard Ubuntu Linux. For the CUPS web interface as how by your screen shot I do not see the status messages as a problem. The show which printers are busy doing a job (did they actually do a job when you have taken the screenshot?). They are not marked as errors and they are not annoying pop-ups which interrupt the user's workflow. If they are not there anymore in newer Mate/Ubuntu/CUPS versions then the upstream developers of CUPS have done changes. Note that the changes in system-config-printer only eliminate annoying desktop pop-ups, they do not change anything in the web admin interface of CUPS. So recommend the system-config-printer upgrade only if the user is complaining about desktop pop-ups. Doing the update does not cause any known regression or side effect, so updating is no problem. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to system-config-printer in Ubuntu. https://bugs.launchpad.net/bugs/1656790 Title: print-notifications: Don't show error for job in progress Status in ubuntu-mate: Invalid Status in mate-settings-daemon package in Ubuntu: Invalid Status in system-config-printer package in Ubuntu: Fix Released Bug description: Running Ubuntu MATE 16.04.1 LTS Every single time I print something, I get an error notification. Unfortunly, I'm running a Norwegian desktop, so this will be a translation of what I suppose the notification says on an English desktop: Printer error Printer 'NAME':'cups-waiting-for-job-completed' It is a bit annoying, but it disappears after a couple of seconds, when the print job is done. After a bit of Googling, I found this is a known error from earlier, with gnome-settings-daemon. I guess the fix never have been included in mate-settings-daemon ? This is the bug in Red Hat for the same problem: https://bugzilla.redhat.com/show_bug.cgi?id=1207154 This is the patch for gnome-settings-daemon from May 20 2015 : https://mail.gnome.org/archives/commits-list/2015-May/msg03447.html The 'cups-waiting-for-job-completed' is a notification in Cups, which should not be ignored by gnome-settings-daemon.
